One question about topology change in optical networks

["Haisang Wu" <hswu@ns.6test.edu.cn>]

Hi, all:
  I need some kind advice and help in Optical Traffic Engineering. 

  In MPLmS Traffic Engineering, underlying resource can be adjusted 
so as to allow providers to change a network topology in response 
to changing traffic patterns. In this case routers or other devices 
that need to interoperate are connected in many ways. It's a bit 
like a highway system where you can add and remove roads at will.
  My question is, has this approach been deployed in ISPs or has any
R&D been conducted on this? Where could I find some articles about
related algorithms and methods?
  Thank you very much .

Best
Haisang
